 SCAT, a parameter proposed by Shaar and Tauxe (2013) in an effort to reduce the number of parameters used to quantify a paleointensity estimate; GAPMAX, the gap factor proposed by Shaar and Tauxe (2013), which is a measure of the average Arai plot point spacing and may not represent extremes of spacing; β, a measure of the relative data scatter around the bestfit line and the ratio of the standard error of the slope to the absolute value of the slope (Coe et al. 1978); the maximum angle of deviation (MAD), the scatter of NRM points about the bestfit line (Kirschvink 1980); the deviation angle (DANG), the angle between the freefloating bestfit direction and the direction between the data center of the mass and the origin of the vector component diagram (Tanaka and Kobayashi 2003; Tauxe and Staudigel 2004); FRAC, NRM fraction used for the bestfit line on an Arai diagram determined entirely by vector difference sum calculation (Shaar and Tauxe 2013); n, the number of the selected samples; H_{
δ
}%, the value of the coefficient of variation
